Finish Grinding Industrial Efficiency Technology Measures
In the finish grinding, clinker is mixed with gypsum and other minerals, such as blast furnace slag, according to the specifications of desired end products and are ground, or milled, to achieve required particle fineness Finish grinding accounts for nearly 40% of the electricity use in cement production (ECRA, 2009)Feb 01, 2009 Surface grinding is used to produce a smooth finish on flat surfaces It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smoothSurface grinding WikipediaMar 01, 2006 For a fineness of 3500 cm 2 /g, the optimal operating variables corresponding to a maximal grinding energy efficiency of crude material were found to be: d¯B = 24 mm, N = 65 rpm, U = 075 and J = 038Energy efficiency of cement finish grinding in a dry batch
